2 Installation Height and Angle
A key factor in optimal performance for SAFR SCAN is the mounting height and angle. Mounting angle refers to the orientation of the camera. The ideal performance is achieved when the subject is directly in line of the camera which is located on the front face of SAFR SCAN.
SAFR SCAN should be installed at a height of 46 to 58 inches (115 to 150cm) to the center of the device. Device should be placed with following considerations:
- As much as possible, place device so line of sight of camera is in line with foot traffic approaching the door.
- When possible, place device so that subject is 3 feet (1 meter) away and in line of sight of the camera when their hand is placed on the door and ready for entry.
- When necessary, line of sight of the camera should be away from bright light sources such as large outdoor windows or bright light sources.
- Mounting with vertical angle (Wedge Mount angled up), this results in recognition working best when subject’s face is in line with the vertical angle of the device face. Subjects may tend to get too close to the reader causing poor recognition performance. Therefore, it is not recommended to mount the device with wedge angled up.
Ideal mounting height is 55 inches (140cm) to the center of the device. At this height SAFR is able to work for subjects as low as 2 feet (1m) and as high as 8 feet (2.5m) at a distance of 4 feet from the reader. The following diagram demonstrates the range with SCAN mounted at 55 inches.
